Ahead of its Sundance debut, Magnolia Pictures and Paramount Pictures have partnered up to bring Joe Swanberg's "Happy Christmas" to audiences worldwide.

The film world premieres at the festival this Sunday. It stars Anna Kendrick, Lena Dunham, Melanie Lynskey, Mark Webber and Swanberg. Magnolia will handle US theatrical and VOD distribution, while Paramount will handle US DVD/Blu-ray distribution and all international rights. Magnolia distributed Swanberg's "Drinking Buddies," which premiered at SXSW last year.

Here's the official synopsis per Magnolia and Paramount:

Anna Kendrick plays Jenny, an irresponsible 20-something who comes to
Chicago to live with her older brother Jeff (Swanberg), a young
filmmaker living a happy existence with his novelist wife Kelly
(Lynskey) and their two-year-old son. Jenny’s arrival shakes up their
quiet domesticity as she and her friend Carson (Dunham) instigate an
evolution in Kelly's life and career. Meanwhile, Jenny strikes up a
rocky relationship with the family’s baby sitter-cum-pot dealer
(Webber).

"I'm excited to continue my relationship with the innovative people at Magnolia and to start a new relationship with Paramount," said Swanberg. "'Happy Christmas' is a personal and important film for me and I can't imagine better partners to help connect it with audiences around the world."
